A large inverted light-bulb-shaped steel structure called "the drywell" is constructed of a steel liner and a concrete drywell shield wall enclosing the reactor vessel--this is considered the "primary" containment.. The atmosphere of the drywell is connected through large diameter pipes to a large hollow doughnut-shaped pressure suppression pool called "the torus", or wetwell, which is half-filled with water. In the event of a loss-of-coolant-accident (LOCA), steam would be released into the drywell and directed underwater in the torus where it is supposed to condense, thus suppressing a pressure buildup in the containment.
The outer concrete building is the "secondary" containment and is smaller and less robust (and thus cheaper to build) than the containment buildings used at most reactors.
As early as 1972, Dr. Stephen Hanauer, an Atomic Energy Commission safety official, recommended that the pressure suppression system be discontinued and any further designs not be accepted for construction permits. Hanauer's boss, Joseph Hendrie (later an NRC Commissioner) essentially agreed with Hanauer, but denied the recommendation on the grounds that it could end the nuclear power industry in the U.S.
...the three original AEC memos, including Hendrie's:
November 11, 1971: outlines problems with the design and pressure suppression system containment.
September 20, 1972: memo from Steven Hanauer recommends that U.S. stop licensing reactors using pressure suppression system
September 25, 1972: memo from Joseph Hendrie (top safety official at AEC) agrees with recommendation but rejects it saying it "could well mean the end of nuclear power..."
In 1976, three General Electric nuclear engineers publicly resigned their prestigious positions citing dangerous shortcomings in the GE design.
An NRC analysis of the potential failure of the Mark I under accident conditions concluded in a 1985 report that Mark I failure within the first few hours following core melt would appear rather likely."
In 1986, Harold Denton, then the NRC's top safety official, told an industry trade group that the "Mark I containment, especially being smaller with lower design pressure, in spite of the suppression pool, if you look at the WASH 1400 safety study, you'll find something like a 90% probability of that containment failing."
PressTV - 'N-waste to haunt US for generations'
...electricity is merely a fleeting by-product of nuclear power plants. The real legacy -- the lasting product of nuclear power plants -- is nuclear waste, which will be a hazard to future generations who will not get one watt of electricity, but will get this toxic legacy for millions of years.
If they cannot be bothered to find a permanent storage for their waste or even transfer if to dry cask storage now, when they are generating electricity and profits from it every day, what are the chances of that happening in the future when the plant is closed, the people who profited from it long dead or moved away, the area too radioactive to work in? Instead of pushing nukes by subsidizing insurance for tens of billions of dollars, Obama should push them to maximize the dry cask storage as Germany has done.

Prime Minister Naoto Kan's government on Friday instructed parts of Fukushima Prefecture outside the 20-km no-go zone around the crippled No. 1 nuclear plant to evacuate by the end of May, saying that cumulative radiation levels may pose a health risk to residents.
